The numerical value of "17" is tet+vav+bet=9+6+2=tov=good.
Why the letter tet (tov=good) did not appear in the first set of tablets, but only in the second? So that nobody would say, when the first set of tablets was broken, "end of good for Israel". Instead, this good begins only with breaking of the tablets. That is why Aaron said, "Feast to Hashem tomorrow'. Because in the future, this day will indeed be a big celebration for Israel.
To be continued!
